Description

远程呈现系统中多显示器滚动显示方法及装置、 处理终端 技术领域
本发明涉及多显示器滚动显示技术, 尤其涉及一种远程呈现系统中多 显示器滚动显示方法及装置、 处理终端。 背景技术
随着会议系统的发展, 人们已经不满足基本会议内容沟通的需求, 更 加追求沟通的舒适度及临场感。 针对此需求发展起来的远程呈现会议系统, 比如网真系统, 是一种沉浸式虚拟会议技术, 能为与会者提供很好的临场 感, 包括真身大小、 眼神交流、 听声辨位等, 营造一种沟通双方面对面的 感觉。 要提供真人大小的图像, 在现有技术条件下, 很难通过每个会场使 用一个摄像头加一个会议终端显示器的方式实现。 因此, 当前远程呈现系 统一般采用在每个会场布置多个摄像头, 并支持同时显示多路视频流。 图 1 为三显示屏网真会场布置示意图, 如图 1 所示, 包括三个并排设置的显示 器 101, 与显示器 101对置的网真桌 102及网真椅 103等, 通过上述布置, 能达到显示的真人比例和现场视角范围, 能提供更加真实和临场感的声音 及图像。 由于普通会议系统某个会场都是一个终端配合一个显示器, 因此 原有滚动字幕都是支持在一个显示器上滚动显示。 针对网真单会场多个显 示器的情况, 原有的方案只能控制滚动字幕或者图像出现在某一块屏幕上, 用户使用并不友好, 如果能够使字幕或图像在多个显示器上依次滚动, 滚 动效果相当于多块显示器是一个整体, 从而给用户更好的体验。 发明内容

本发明的基本思想为, 接收到需滚动显示的内容时, 根据所述远程呈 现系统的显示器排列方式、 输出大小及滚动显示方式确定所述需滚动显示 的内容在各显示器中的显示位置及显示内容, 并分别与各显示器原有解码 输出显示的内容加权叠加, 作为各显示器当前帧输出; 确定是否显示到时 或取消滚动显示, 是时结束当前处理, 显示未到时且未取消滚动显示时, 根据所述远程呈现系统的显示器排列方式、 输出大小及滚动显示方式确定 所述需滚动显示的内容在各显示器下一帧的显示位置及显示内容, 分别与 各显示器下一帧原有解码输出显示的内容加权叠加, 作为各显示器下一帧 输出。
为使本发明的目的, 技术方案和优点更加清楚明白, 以下举实施例并 参照附图, 对本发明进一步详细说明。
图 2 为本发明实施例的远程呈现系统中多显示器滚动显示方法的流程 图, 如图 2所示, 本示例的远程呈现系统中多显示器滚动显示方法包括以 下步骤:
步骤 201,接收到需滚动显示的内容时, 根据所述远程呈现系统的显示 器排列方式、 输出大小及滚动显示方式确定所述需滚动显示的内容在各显 示器中的显示位置及显示内容, 并分别与各显示器原有解码输出显示的内 容加权叠加, 作为各显示器当前帧输出。
通过远程呈现系统的远程配置接口 (如 web方式或者控制台或者遥控 器等)配置需要显示的字幕, 例如字幕 "会议结束后请大家分组讨论"; 配 置显示滚动速度及滚动方向等参数, 本示例中采用自左向右滚动的方式。 本发明中, 所谓字幕即以点阵显示的文字。 当然, 根据需要, 也可以直接 显示普通文字, 只是现场效果一般而已。
根据用户配置以及远程呈现系统的自身的触发方式将滚动字幕消息发 送给各个会场。
当前会场的处理终端接收到该滚动字幕消息后, 在内存中将该滚动字 幕消息解析为准确的需要与显示器中当前输出显示内容叠加的点阵图像, 具体方式为通过处理终端预置的点阵字库将滚动字幕解析为可以直接输出 显示的线性码流。
本发明中, 滚动显示的也可以是图像等显示内容。 其处理方式与滚动 字幕的处理方式完全相同。 这里不再专门列举滚动显示图像的示例。
处理终端在内存中虚拟出远程呈现系统当前的显示器的排列位置及显 示器显示窗口的大小。 本发明中, 远程呈现系统的显示器为多个, 一般而 言, 这些显示器均如图 1 所示那样单层线性排列, 当然, 本发明的技术方 案也支持多层排列方式, 其所实现的原理与单层线性排列的实现方式完全 相同, 只是计算显示帧时的计算方式略有不同而言。 因此, 本发明仅以图 1 所示的远程呈现系统的显示器数量及其排列方式为例进行说明。 本发明中, 为提升滚动显示的效率, 可以将显示器的排列方式及其显 示大小等参数作为配置参数输入到处理终端的内存中, 处理终端使用时直 接调用该配置参数即可。 当然, 也可以仅输入基本参数如显示器的大小、 各显示器之间的排列顺序等, 处理终端根据这些配置参数计算显示的相关 参数。
根据当前时刻实时计算出滚动字幕显示在各个显示器的当前位置和内 容的方式如图 3、 图 4所示, 即虚拟出相应的坐标系, 计算各显示器在坐标 系中的位置, 根据需显示的字幕的大小及在显示器中显示字幕的位置, 确 定出需滚动显示的字幕中各个字在当前帧的显示位置。 如图 3、 图 4所示, 当确定出各显示器的排列顺序, 显示器自身的长、 宽尺寸, 滚动字幕的大 小及滚动方向等参数时, 确定滚动字幕当前帧在各显示器上的显示位置, 各显示器的显示内容, 是容易实现的。 本发明不再赘述其确定细节。
本示例中, 滚动显示的方式是从左向右滚动显示, 本发明并不限定滚 动显示的方式, 例如也可以是从右到左滚动显示。 当然, 如果显示系统是 双层或更多层线性排列的显示器, 可以分层分别显示滚动字幕, 或者是分 层共同显示相应的滚动字幕。 由于这些显示方式都是通过具体的数学运算 即可实现, 显示的方式有很多种, 本发明不可能——赘述。
根据三个显示器对应区域欲显示出的字幕内容, 分别与各显示器的解 码器解出的线性码流加权叠加后输出。 也就是说, 将需滚动显示的字幕在 各显示器中的显示位置及显示内容, 分别与各显示器原有解码输出显示的 内容加权叠加, 作为各显示器当前帧输出。
步骤 202, 确定是否显示到时或取消滚动显示, 是时结束当前处理, 并 在显示未到时且未被取消滚动显示时, 根据所述远程呈现系统的显示器排 列方式、 输出大小及滚动显示方式确定所述需滚动显示的内容在各显示器 下一帧的显示位置及显示内容, 分别与各显示器下一帧原有解码输出显示 的内容加权叠加, 作为各显示器下一帧输出。
本发明中, 当前帧输出后, 需要确定当前滚动显示的字幕是否到时, 或者是否已被用户取消显示, 如果滚动显示的字幕显示到时或已被用户取 消显示时, 当前处理结束。 而滚动显示未到时且未被取消滚动显示时, 需 要根据滚动显示的速度, 确定下一帧滚动字幕应在各显示器的显示位置及 显示内容, 并与各显示器下一帧原有解码输出显示的内容(各显示器的背 景显示内容可能未变化)加权叠加, 作为各显示器下一帧输出。
并且, 在上述确定的下一帧作为当前帧输出显示后, 重复步骤 202, 直 到滚动显示到时, 或被取消滚动显示。
图 5 为本发明实施例的远程呈现系统中多显示器滚动显示装置的组成 结构示意图, 如图 5 所示, 本示例的远程呈现系统中多显示器滚动显示装 置包括接收单元 50、 第一确定单元 51、 叠加单元 52和输出单元 53, 其中: 接收单元 50, 配置为接收需滚动显示的内容;
第一确定单元 51, 配置为根据所述远程呈现系统的显示器排列方式、 输出大小及滚动显示方式确定所述需滚动显示的内容在各显示器中的显示 位置及显示内容; 关于确定需滚动显示的内容在各显示器中的显示位置及 显示内容的方式, 可参见图 3及图 4所示的确定方式。
叠加单元 52, 配置为将各显示器中的需滚动显示的内容分别与各显示 器原有解码输出需显示的内容加权叠加;
输出单元 53, 配置为将叠加后的内容作为各显示器当前帧输出。
